Hi all,

I don't know how familiar you are with OSGi, but I thought I'd give this
one a go...
Would it be possible to connect to HBase from an OSGi (Spring Dynamic
Modules) application? I'm not familiar with the background of
classloading etc, so I can't figure this one out on myself. Perhaps one
of you has some experience in this field...

Thanks in advance,

Niels

Bundling together all the jar to run HBase under OSGi might be a challenge but I don't see why it wouldn't work. I've never used Spring DM, just Felix.

Yes you can, I use Felix and Eclipse Virgo Blueprint in my app, and it connects to HBase. The HBase and Hadoop jars are not bundles, however, so you will need to either put them on the boot classpath, package them inside your bundle jar, or turn them into bundles yourself.

Thank you for your answers! I got a bit further, yet now I'm struggling
with zookeeper. I'm getting a NullPointerException when calling
ZookeeperWrapper.getZookeeperClusterKey.

Any ideas on what this means? Could this be a configuration problem?

Kind regards,

Niels
